Updating SCMS 7.1> 7.5

Hello everyone,

I am creating a test environment compared to a client that has SCMS 7.1 and is planning to upgrade to version 7.5.
I want to evaluate the behavior in a laboratory but I do not have the average of SMCS 7.1 the Symantec Installation Manager of that version to be able to simulate the update before arriving with the corporate client.

Someone could provide me with the installation average of SCMS 7.1 in order to update to version 7.5.

Thank you very much
Regards.
